Referring to http://tools.ietf.org/html/draft-ietf-roll-trickle-mcast-02 
section 4.1 - maybe I'm missing something but why is the 'S' field 
needed? Given that the text for Opt Data Len is wrong (it should say 
"Length of the Option Data field in octets.  MUST be set to 2, 4, 10 or 
18"), surely Opt Data Len is sufficient for working out which Seed IDs 
are in there?
